Polarizing Beam Splitter

Application ID: 31041

Polarizing beam splitter cubes consist of two right-angled prisms where a dielectric coating is applied to the intermediate surface. The cube transmits part of the incident wave while reflecting the other part. An advantage of using this cube design, instead of a plate design, for beam splitters is that ghost images are avoided.

This new app demonstrates the basic MacNeille design, which consists of pairs of layers with alternating high and low refractive indices, and where you can select how many layers will make up your splitter. You can enter refractive indices for the prisms and the layers in the dielectric stack, either directly or through a predefined material list.

Sweeps can be performed over a range of wavelengths or spot radii. The app displays the norm of the total electric field and the electric field for the first and second wave for a given wavelength or spot radius and polarization. Also presented is the reflectance and transmittance.

This application example illustrates applications of this type that would nominally be built using the following products:
